A Long Time Ago Spiretone Had ...
A long time ago Spiretone had an adaptor that you could attach to a
telephoto SLR lens that would convert it to a telescope, i.e., with no
camera attached. I can't remember what they called it to see if i
could look up on google.
What were they called?
Where can I buy a functional equilvant today, Nikon mount?
thanks for the help
